DETAILED DESCRIPTION

Reference now will be made in detail to embodiments, one or moreexamples of which are illustrated in the drawings. Each example isprovided by way of explanation of the embodiments, not limitation of thepresent disclosure. In fact, it will be apparent to those skilled in theart that various modifications and variations can be made to theembodiments without departing from the scope or spirit of the presentdisclosure. For instance, features illustrated or described as part ofone embodiment can be used with another embodiment to yield a stillfurther embodiment. Thus, it is intended that aspects of the presentdisclosure cover such modifications and variations.

The light kit of the present disclosure can provide numerous technicalbenefits. For instance, positioning the light source to illuminate theedge of the panel allow for light to be uniformly distributed throughthe diffuser of the light kit. In this manner, the appearance of severallight sources each individually emitting light can be avoided.Furthermore, positioning the light source to illuminate the edge of thepanel makes the light kit suitable for low profile lightingapplications.

As used herein, a “light kit” refers to a device used to provide lightor illumination using one or more light sources. In addition, the terms“first” and “second” may be used interchangeably to distinguish onecomponent from another and are not intended to signify location orimportance of the individual components. Furthermore, the use of theterm “about” in conjunction with a numerical value is intended to referto within 25% of the stated numerical value.

Referring now to the FIGS., FIGS. 1 through 3 depict a ceiling fan 100according to example embodiments of the present disclosure. The fan 100may be removably mounted to a ceiling 110 separating a first space 112(e.g., positioned beneath the ceiling 110) from a second space 114(e.g., positioned above the ceiling 110). In some embodiments, the fan100 includes a plurality of fan blades 130. As shown, each the pluralityof blades 130 may be coupled to a blade hub 132. More specifically, eachof the blades 130 may be coupled to the blade hub 132 via a blade arm134. It should be appreciated that the blade arm 134 may be coupled tothe blade hub 132 and a corresponding fan blade 130 via a suitablefastener (e.g., screw, bolt, etc.). As shown, the fan blades 130 may becoupled to the blade hub 132 via the blade arm 134 such that the fanblades 130 are spaced apart from one another along a circumferentialdirection C.

In some embodiments, the fan 100 includes an electric motor 140. Themotor 140 may be configured to receive an input power from a powersource, such as an alternating current (AC) power source or a directcurrent (DC) power source. Furthermore, the motor 140 may be operativelycoupled to the blades 130 via the blade hub 132. In this manner, themotor 140 may convert the input power into mechanical energy needed todrive rotation of the blades 130 along the circumferential direction C.In some embodiments, the motor 140 may be configured to drive rotationof the blades 130 in a first direction D₁ or a second direction D₂ thatis different than the first direction D₁. For example, the blades 130move air in the first space 112 towards the ceiling 110 when rotated inthe first direction D₁. Conversely, the blades 130 may move air awayfrom the ceiling 110 when rotated in the second direction D₂. Morespecifically, the blades 130 may move air towards a floor 116 definingthe first space 112.

In some embodiments, the fan 100 includes a fan motor housing 150configured to accommodate the motor 140. More specifically, the motor140 may be positioned within a cavity 152 defined by the fan motorhousing 150. In addition, the fan 100 may include a cover 154 that maybe coupled to the fan motor housing 150. In particular, the cover 154may be coupled to the fan motor housing 150 such that the motor 140positioned within the cavity 152 may be hidden from view.

As shown, the fan 100 may be suspended from the ceiling 110 via adownrod 160 having a first end 162 and a second end 164. It should beappreciated that the first end 162 and the second end 164 may be spacedapart from one another along a length L of the downrod 160. In someembodiments, the first end 162 of the downrod 160 may be coupled to asupport (e.g., mounting bracket) positioned within the ceiling 110 orthe second space 114. In addition, the housing 150 may be coupled to thesecond end 164 of the downrod 160.

In some embodiments, operation of the fan 100 is controlled by a controlsystem 166. The control system 166 may include a wall-switch that may bemanipulated to selectively couple the motor 140 to a power supply. Inthis way, the control system 166 may selectively activate (e.g., turnon) or deactivate (e.g., turn off) the motor 140 to control rotation ofthe blades 130. In some embodiments, the control system 166 controlsoperation of other devices. For instance, the control system 166 may beconfigured to adjust a position of window blinds (not shown) in thefirst space 112. More specifically, the control system 166 may adjust aposition of the window blinds to or towards a fully open position or afully closed position. In this way, an amount of natural light enteringthe first space 112 through one or more windows is controlled.

Referring now to FIGS. 4 and 5 , the fan 100 may include a switchhousing 170 coupled to the fan motor housing 150. In particular, theswitch housing 170 may be coupled to the fan motor housing 150 such thatthe fan motor housing 150 is positioned between the ceiling 110 and theswitch housing 170.

As another example, the LED light sources222 may be configured to emit light having a color temperature of about5000 K.

In some embodiments, the light kit 200 includes a driver circuit 230.The driver circuit 230 may, for instance, receive an input power from apower source (e.g., mains power supply) via the conductors 178 (FIG. 5 )positioned within the switch housing 170. The driver circuit 230 may beconfigured to convert the input power to a driver current suitable forpowering the light source 220. The driver circuit 230 may includevarious components, such as switching elements (e.g., transistors). Gatetiming commands may be provided to the one or more switching elements toconvert the AC input power to the driver current. In some embodiments,the driver circuit 230 is potted. In other embodiments, the drivercircuit 230 is not potted.

In example embodiments, the driver circuit 230 adjusts the driver outputbased, at least in part, on a dimming control signal (e.g., 0V to 10Vdimming control signal). More specifically, the dimming control signalmay be indicative of a voltage (e.g., 0V to 10V) at a control input ofthe driver circuit 230. For example, reducing the dimming control signalby 50% may result in a corresponding reduction in the driver outputprovided to the light source 220. The reduction of the driver output mayreduce the overall driver current for supply to the light source 220. Asa result, the lumen output of the light source 220 may be adjusted(e.g., dimmed) by varying the dimming control signal.
